A really annoying problem, when you edit a stack build by making direct steps.
Edit a cue on the desk, then, on the laptop, modify times, then press some "go". Return to a modified step and edit it again. The levels are often back to the previous levels.
Sometime you need to edit them, 2 or 3 times to make it works.
It's quite difficult to explain... maybe someone wiht a good english could explain it better.
